Abstract An efficient one-pot method was developed for the synthesis of 2-(1,2,4-oxadiazol-5-yl)anilines via the reaction of amidoximes with isatoic anhydrides in a NaOH–DMSO medium at ambient temperature. The method allows to obtain structurally diverse substituted anilines bearing the 1,2,4-oxadiazole motif in moderate to excellent yields without the utilization of protective groups. The reaction
